Can a proof-of-work estimate the mixing time of a Rubik's cube?

Can a proof-of-work estimate the mixing time of a Rubik's cube? Forgive the flight-of-fancy; if this is too far-fetched I will delete. To start off, as of now (1d6e05de09721d4d56107ffbcf54dc557b881e7c83ae36) the number of hashes performed every ten minutes, about 2^71 or so, is not that far off from the order of the Rubik's cube group, about 2^68 or so. That is, presently Bitcoin miners perform slightly more hashes every 10 minutes than the number of positions on a 3x3x3 Rubik's cube. Elements of the Rubik's cube group are usually written as a combination of moves on the 6 faces (front, back, down, etc.) A move is often called an "algorithm" in cube terminology, or a "word" in discussions about group theory. Thus, each algorithm can be written as a string of moves, e.g. FUDF^2B^-1, etc. The "mixing time" tau of the Rubik's cube group is the estimated number of scrambles that are needed to go from the solved position to a "random

Detecting Wash Sales/Transactions

Detecting Wash Sales/Transactions I run a site which is essentially an e-commerce platform where buyers connect with sellers and all transactions happen in Bitcoin. I worry about sellers on the site continuously buying their own items on the site to gain visibility (more sales means higher ranking on the front page). Is it possible to detect whether an incoming transaction originated from the same bitcoin wallet? I am thinking that I could run a tree/graph traversal of the transactions starting at a given address and see if I end up at that same address again. But I'm not sure how this would work with wallets where each payment generates a new address from a master public/private key pair. PS: Maybe wash sale is not the correct term here. https://ift.tt/2KzEQYO

Accidentally sent BCH to BTC address... I tried to use the private keys in a BCH wallet to recover, and there's no coins showing

Accidentally sent BCH to BTC address... I tried to use the private keys in a BCH wallet to recover, and there's no coins showing I've read many other threads like this and it seems to be the common consensus that to recover BCH sent to a BTC address, just use the private key inside a BCH compatible wallet. Well, I did that, and there are no coins showing, nor the address that I originally sent the BCH to (which has 100+ confirmations already). Not really sure what to do in this case. The wallet which I originally sent the BCH to was a Bitcoin wallet in the Copay app. https://ift.tt/2lIKIRu

How to generate an HD wallet or use existing one for generating new addresses

How to generate an HD wallet or use existing one for generating new addresses I am trying to create a simple application to play with bitcoins. I want to generate a new address every time it is requested. I know what the HD Wallet is, but doesn't have much experience working with all this stuff. I have two ways, as far as I know. Create a new HD wallet, maintain it locally and use it for generating new addresses Using extended public key (XPUB), or what is the valid name for that term. The main idea is to keep it secure, therefore the second variant will be better I think. Generally I want to be able to change something (maybe XPUB), that is used to generate new bitcoin addresses, from admin panel and then this "something" will be passed to a script that will be responsible for generating new addresses. Could someone explain all the steps required to do this from programming point of view? And please tell me, why it is dangerous to create a new wallet locally

In their case, will not they get any reward and also any fees?

If it is like that, all the blocks in that time frame, are they the same? Thanks! https://ift.tt/2Kva7Mw

Is Bitcoin stateless? Do miners keep track of current 'state' of bitcoin blockchain?

Is Bitcoin stateless? Do miners keep track of current 'state' of bitcoin blockchain? In Ethereum or EOS, concept of Accounts make it important to keep track of 'current state'. (e.g.) current balance of Account A is 300 EOS. Especially in Ethereum, roothash of state tree is stored in every block. Bitcoin, on the other hand, doesn't care nor store information of current state. I know wallet applications gather block data and derive current balance of the user.

Unspent/Spent Flag in Blockchain

Unspent/Spent Flag in Blockchain I just started getting interested in the blockchain a week ago, however there is something I can not just figure out. Regarding the flag "Spent/Unspent" in transactions. I get that we flag "spent" the output of a transaction if this same output is used as an input in a future transaction. -Suppose that we make a transaction (transaction 1), and this transaction get included in the blockchain (let's say block 1). We do not spent the output (consider a simple transaction single input & a single output) until 100 blocks later (transaction 2) in the blockchain. I understand that in transaction 2, in the inputs, there is the info of the previous transactions (since we are implementing hash pointers)like shown below in "prev_out" (JSON format of transaction extracted from Blockexplorer api) : 'inputs': [{'prev_out': {'addr': '1PFtrRjbq4aLfM7k4tyLZ3ZAuTsgLr6Q8Q', 'n': 0, 'scr

How do you find the signing message of a TxIn signature? [NOT a duplicate] [duplicate]

How do you find the signing message of a TxIn signature? [NOT a duplicate] [duplicate] This question already has an answer here: How to redeem a basic Tx? 3 answers So I'm trying to find m in s = (m + r * x) / k of a Bitcoin transaction input. Taking a look at this transaction , I can pull out s and r from the ScriptSig of an individual input: 30 45 02 21 00c717169b0055cf66d79d4cc59d05ce220341efd80985fa30bbfa88e9b69ecfb0 <--- r 02 20 10dbe3a7e3bc3201df8a42081c869f981bdd9d3e465f5fc483eaafab82f1ce7c <--- s 01 I know x is the PrivateKey and k is the Ethereal PrivateKey. But I can't seem to figure out m. I know it's a double sha2 hash of some message that produces r and s, but where it comes from or how it's put together seems a mystery. I've spent days stepping through NBitcoin's source code but I'm pretty lost. What makes it confusing is a bunch of things (versions, prev out, script sigs, sequences, etc) are hashed for the transaction as a whole

Issue with getrawtransaction txindex and reindex

Issue with getrawtransaction txindex and reindex I am running Bitcoin Core Deamon version v0.16.0.0 on Ubuntu and need to call the getrawtransaction command for some TX. To use the getrawtransaction I need to run bitcoin core with txindex=1. But if I am running with txindex=1 it says that I have to run the core with reindex or reindex-chainstate. So I did run first bitcoind -reindex-chainstate and then bitcoind -txindex=1 and it still says that I have to run with reindex or reindex-chainstate. So I tried to run bitcoind -txindex=1 -reindex-chainstate but still says run it with reindex or reindex-chainstate. Now I am running bitcoind -txindex=1 -reindex Is this the correct way? And is it normal that bitcoin-cli getblockcountis stuck on 0? https://ift.tt/2KuNNzA

Why is the probability of finding a winning nonce exactly the same for a new header and a header where you've already tried 1 billion nonces?

Why is the probability of finding a winning nonce exactly the same for a new header and a header where you've already tried 1 billion nonces? I'm referring to this question: When do miners stop waiting for new transactions? More specifically, this statement from the top answer: "suppose you have a block header h1 on which you have already tried a billion nonce values, and a header h2 which has just been generated and on which no nonces have been tried yet. If you have the choice as to which one to hash next, which should you choose, for the greatest chance of finding a winning nonce? The answer is, it makes no difference - they both have exactly the same probability. So there is no harm in switching to h2" I would have thought that the probability would be slightly higher for the first block (h1) as there are 1 billion nonces that you know do not succeed, i.e. fewer winning possibilities. Complete newbie here and to the bitcoin world so apologies if I'm missin

Does fees on Lightning network scale with transaction size?

Does fees on Lightning network scale with transaction size? I did some reading around and various sources claim that the fee is proportional to the amount you would like to route. One source says that the fees are a flat fee + a certain percentage of your transaction amount. Intuitively it makes sense that the fee should scale with the transaction size since a large transaction requires the intermediate routing nodes to temporarily 'freeze' up a larger amount in their channel, and/or creating a larger inbalance in their channels, which is of course not desirable. So does anyone know exactly how fees scale with transaction size in the LN, or actually has equations to calculate it? https://ift.tt/2lBa8Aw

How this is possible to generate blocks with no transactions? I found this block in blockchain explorer. It is pretty well confirmed, but it has no transaction inside, except "Newly Generated Coins" one. How this can be possible and what for? Additional question: If this is so easy to generate such blocks, what stops miners to generate these (lightweight) blocks as many as possible to earn new bitcoins? Thanks. https://ift.tt/2yIMSdl

Checking the first and last characters of a cryptocurrency address?

Checking the first and last characters of a cryptocurrency address? When confirming that an address entered on a site/app is what I expect it to be, I often check the first and last 3-4 characters to see if they match. Is this practice dangerous? Could an attacker feasibly generate an address that matches at the beginning and end, but is different in the middle? https://ift.tt/2KjHzlI

CoinCalculators is a New Mining Profitability Calculator Service With mining profits diminishing lately it is always a good idea to be on a lookout for new and profitable coins to mine, regardless if you are using GPUs or ASIC miners. So you might want to give the Coin Claculators service a try and see if you can find something new and interesting. It tracks close to 300 crypto coins and can mining profitability calculators available for GPU miners with presets for the hashrate for the more common AMD and Nvidia GPUs as well as ASIC miners with presets for S9, L3+ and D3. You can of course also set your own hashrates for each algorithm, so you are not limited only to the presets available, though they help for a quick check. There is also a Dual Mining profit calculator, however it is a bit limited in functionality. There are also individual mining profitability calculators available for the supported coins for when you are not looking what is most profitable to be mined. There is als

How message propagation works in bitcoin - please somebody help :)

How message propagation works in bitcoin - please somebody help :) Basically I know how message propagation works in peer-to-peer bitcoin network. But I need a clarification on three points below: QUESTION 1: In bitcoin network every node relays every message it received to it's peers. If node A received message X and relayed it to his peers, and those peers relayed it to theirs, can we take for granted that finally this message X will return to node A like a boomerang? Because if every node relays every message, it should finally. QUESTION 2: I know there is no feature in bitcoin client for this, but let's suppose there was one. If node A would like to know if message X was ever relayed on the network, and there would be a feature that allowed to ask it's peers if they had ever received X, and once enough number of peers answered that they do indeed relayed such X, would it imply that all connected (at the time when X was relayed on network) nodes received X? Because if

How does Bitcoin comply to GDPR

How does Bitcoin comply to GDPR In the data world GDPR is currently a very hot topic: personal data must be protected and not retained too long. For normal companies and systems it is already very difficult to meet the letter of the regulation in practice, however I image that for bitcoin it is even challenging on a much deeper level. Two core principles: Data must be visible by all The full history must be preserved This brings me to a question: How does Bitcoin respond to the introduction of GDPR? And as bonus question: What does this mean for other blockchain applications (like corporate concepts, not specifically for currencies) https://ift.tt/2KdRd9L

Also, I don't speak/write in English well, so please excuse me if I'll make some mistakes. I) Peer-to-peer network with private messages Let's presume that in a peer-to-peer network we want to send private message. So, a sending node: 1) signs his message (to authenticate source) 2) then encrypts it using symmetric cryptography 3) then encrypts the symmetric key (which will be used to decrypt the message) using public key of the recipient 4) and then on top of that he signs using his key both the message encrypted and symmetric key So, finally, we have 2 things: 1) Message -> Signed by his private key

How single usage of bitcoin address is resistant to quantum computing _and_ replace-by-fee?

How single usage of bitcoin address is resistant to quantum computing _and_ replace-by-fee? It is often said that if a bitcoin user uses addresses only once, then quantum computer cannot compromise their security since the public key is revealed only when the money are actually spent.

Running a full node in the cloud - on top of FUSE/s3 filesystem

Running a full node in the cloud - on top of FUSE/s3 filesystem I'm trying to figure out the cheapest way to run a full node in the cloud (specifically AWS). In terms of compute resources, a t2.nano should probably be enough, after the initial syncing of the block history. However, disk space (EBS) is not that cheap. 200GB will run you ~$20/month. A bit too steep for personal use, in my book. I was thinking of mounting the data dir on S3. 200GB on s3 is several times cheaper, and a few 100ks of IO operations a month is also negligible (cents). The question is whether: anybody has ever tried something like this the bitcoind process has problem with a FUSE file system The above configuration should cost like $5/month (and possibly free if your AWS account's free tier isn't used up by now). https://ift.tt/2tkGGmt

Lightning incentive for micro-cheating?

Lightning incentive for micro-cheating? New to Lightning, and I'm having a hard time understanding something about the incentive system. So, if block sizes remain fixed, and transaction fees become prohibitively expensive one day, owing to future btc popularity, won’t there be an incentive to cheat in channels, knowing that the cost to settle on chain is prohibitive? Who’s going to broadcast a refund transaction that costs (one day, e.g.) $100 in fees, just to claw back a few cents from an uncooperative channel node? Isn’t that an incentive for massive micro-cheating? Sorry if i’m massively misunderstanding how this works. Is there a way to create a channel that guarantees any side can broadcast the refund without incurring extra costs? https://ift.tt/2K9DTmE

Receiving payment in Lightning Network is a big problem?

Receiving payment in Lightning Network is a big problem? There are some requirements to receive Lightning funds. According to here , Nothing can be received immediately after creating a new payment channel, as ‘room’ for incoming funds has to be made by spending some funds first. I would like to be able to receive LN payment on online shop. In order to do this and in my understanding, I have to either wait until my customers fund channels to me, or find a node that already has many channels and get it connect to me with an ample amount of cap. The former way does not make sense because users have to open another channel to my node if they've already opened one. The latter way might work if a big cap node thinks my business would be great and users would come along. Receiving in LN is very difficult and a big problem for merchants. Thoughts on it? Or if my thought above is wrong, please educate me. https://ift.tt/2K2Gset

Value of cryptocurrencies: Why does noone make Bitcoin2, 3, 4,...?

Value of cryptocurrencies: Why does noone make Bitcoin2, 3, 4,...? Cryptocurrency disciplee sometimes say that cryptocurrencies have just as much inherent value and potential as storage of value as fist currencies. One argument specific to the Bitcoin is that its value is guaramteed by the limited number of Bitcoins. However, I am very skeptical about this and similar arguments because of the following reasoning: Why does noone use the exact same technology of the Bitcoin and create Bitcoin 2? If they did, why would a Bitcoin2 be worth less than a Bitcoin? If it isn't, how can there be any worth in a Bitcoin, if there is the possibility that in five years there are a thousand different Bitcoin like system all guaranteeing the same anonymity, reliability, decentralized storage, and ease of use as the original Bitcoin? To me this is a significant difference to classical currencies which are linked to real governments and guaranteed by the fact that these governments work, pay and ar

For me, it runs twice, right off the bat. bitcoin.conf: server=1 daemon=1 maxconnections=12 maxuploadtarget=20 rpcuser=xxxx rpcpassword=xxxx testnet=1 rpcallowip=52.86.xx.xx walletnotify=/home/scripts/transaction.sh %s keypool=10000 transaction.sh: #!/bin/sh F=notify_log D=`date +"%Y%m%d%H%M%S"` echo ${D} - ${1} >> ${F} Produces an output of: 20180126015435 - cf59f4c18a80773164c7efdf2a77722099722b3a61274f940aea52cbd600db2b 20180126015435 - cf59f4c18a80773164c7efdf2a77722099722b3a61274f940aea52cbd600db2b Same TXID, same timestamp. But why twice? https://ift.tt/2M9HWzS

Multisig signrawtransaction fails

Multisig signrawtransaction fails I have 3 private keys (a,b,c) which belong to an address (2 of 3) from which I want to spend funds using RPC commands. I´ve started with generating the redeemScript using createmultisig() and the pub keys which I have generated from the 3 priv Keys (using bitwasp). As the result returns the correct address this step seems to be correct. After importing the address to my node and rescanning the blockchain I execute listunspend() to get the unspend outputs for my rawtransaction. Now I generate the raw tx using createrawtransaction({txid,vout,scriptPubKey,redeemScript},{address:amount}) Here the result: 020000000195b96fa7fff141564feba34cb669bdeb94953c98ae864465623def3fbe9e9fb10100000000ffffffff01e87a01000000000017a9145766fcbfc6927c0b027e4b4245fffcb1ec16f64b8700000000 Now I start with signing this raw transaction signrawtransaction(rawtx,{txid,vout,scriptPubKey,redeemScript},privKey1) The result of this signing process is used for the second st

how long does it take for an mining machine to exhaust 2^32 in minutes and what is the actual speed of mining machines?

how long does it take for an mining machine to exhaust 2^32 in minutes and what is the actual speed of mining machines? Mining is usually about taking the double sha. most if not all mining machines such as bitminer's machines usually give some indications for example 1TH/sec per second. Do they count the double sha as one hash operation or does it mean that they count the double sha as two operations. Wait, even more interestingly, 1 TH/sec means literally 1 terahash per second. Meaning that we can do 1 trillion operations per second ! Does that not mean that I could exhaust a given nonce in less than a second ?! given that we are dealing with only ~4 billion values ? Assuming that within the ~4 billion values there is one that validates the block, we find a solution in less than a second ! So it aint making sense to me that it takes so long and is so difficult to be a successful solo miner. https://ift.tt/2K5MXfy

How to recover wallet by importing private key on testnet?

How to recover wallet by importing private key on testnet? I want to test the functionality of wallet recovery via private key import on the testnet. Preferably thru an online service. I only want to test the functionality so that i can verify that it's basically working since i'm working on some Python code that i want to use on the mainnet later. So for that i don't want to download the whole blockchain but instead want to verify that my private key is generated correctly and i can access the funds that way. But i can't find any possibility to do that on testnet... https://ift.tt/2ypYqlC

I’ve been trying to find someone that offers an opinion (BUY/SELL/HOLD) etc. for Dogecoin [on hold]

I’ve been trying to find someone that offers an opinion (BUY/SELL/HOLD) etc. for Dogecoin [on hold] I started investing in cryptos with Bitcoin and Ethereum, but I think both of those will likely die at some point. The future is in the alt coins, but they’re so volatile that I’ve lost some money already – sold when it was going down, then missed the upswing. So I’m trying to find a site with an opinion and analysis that I can trust. https://ift.tt/2JPbm9J

ECDSA: (v, r, s), what is v?

ECDSA: (v, r, s), what is v? Deterministically signing a Tx with RFC6979 returns v, r, s, where r and s are the 2 values used in standard ECDSA signatures. v = 27 + (y % 2), so 27 + the parity of r, as pybitcointools indicates . So for even r, we get v = 27, odd r we get v = 28. How is the value of v (27 or 28) important? Why is it necessary to have a v value? Also, why is it 27? https://ift.tt/2JZohSw
